Word Origin & History

task c.1300, "piece of work imposed as a duty," from O.N.Fr. tasque (13c., O.Fr. tasche, Fr. tâche) "duty, tax," from V.L. *tasca "a duty, assessment," metathesis of M.L. taxa, a back-formation of L. taxare "to evaluate, estimate, assess" (see tax). General sense of "any piece of work that has to be done" is first recorded 1590s. Verb "to put a strain upon" is from 1590s. Phrase take one to task (1680s) preserves the sense that is closer to tax. Ger. tasche "pocket" is from the same V.L. source (via O.H.G. tasca), with presumable sense evolution from "amount of work imposed by some authority," ...to "payment for that work," to "wages," to "pocket into which money is put," to "any pocket."
